NE spring blvd zone 3, network completion

The Federal Highway Administration (FHWA) awarded the Washington State Department of Transportation $15.1 million under the Highway Planning and Construction program (CFDA 20.205) on February 27, 2025, for the NE Spring Boulevard Zone 3 Network Completion project in Washington. The project entails construction of an extension of NE Spring Boulevard, including a couplet roadway configuration around the Sound Transit 2 line on the east end, with infrastructure improvements consisting of median construction, turn lanes, landscape-buffered sidewalks, and dedicated bike lanes. The scope encompasses a bridge over West Tributary Creek, upgraded and new traffic signals, illumination, Americans with Disabilities Act (ADA) compliant ramps, audible pedestrian crossings, and high-visibility crossing striping.

The project also incorporates environmental mitigation and stormwater management components, including wetland mitigation, stormwater treatment facilities, and storm drainage systems. As a Formula Grant under the Federal-aid Highway Program, this award supports the state's selection and administration of highway infrastructure projects based on statutory allocation formulas. The project is administered by WSDOT and requires Federal Highway Administration division office approval and oversight in accordance with applicable federal planning, design, environmental, and safety requirements.
